What does the Endpoints object for a service contain?

The list of pod IPs and ports that the service routes traffic to.

The list of node IPs that the service is exposed on.

The DNS names of the backing pods.

The ClusterIP and port of the service itself.

What DNS name is automatically created for a service named 'myapp' in the 'default' namespace?

myapp.svc.default.cluster.local

default.myapp.svc.cluster.local

myapp.default.svc.cluster.local

What is the primary purpose of a ClusterIP service?

To provide DNS-based service discovery only, without any load balancing.

To expose a set of pods to external clients via a cloud load balancer.

To assign a static IP to each pod so that other pods can reach it directly.

To provide a stable virtual IP that load-balances traffic to a set of pods within the cluster.

Use ClusterIP, NodePort, LoadBalancer Service Types and Endpoints CKA Practice Questions (Page 3)

Part of the Servicing and Networking domain, which accounts for 20% of the CKA exam. Linux Foundation does not publish an official question count, but from its 120-minute exam (~50–80 total, ~10–16 in this domain), expect 2–3 from this objective — we provide 23 practice questions to prepare you well beyond it.
